Module event_handler 

Incoming event handling, from the first signature check to the timeline.

The service authorizes incoming PDUs, fetches the events they depend on, derives their state and appends them. Observability counters cover the local state build, the previous-event walk and the backoff verdicts. A per-room history keeps the previous-event walk passes for up to three days.
